Classic 150SL following a Classic 150 Lite, Modbus output

[jedon]

I have a Classic 150 Lite that is at capacity so I need another one. I have it hooked up via ethernet and poll modbus data off it using Node-Red. If I get A 150SL that does not have ethernet but if I connect them together can I read the combined data over the ethernet off the classic lite?
Thanks,

 Jedon ,
Don't know the answer to your question but the price difference between the regular Classic and Solar is $63 .  I just looked at the SL brochure and it says it does modbus and can be paralleled with the Classic Lite. So you are wondering if it will send the data to your Lite and then you can get it via network that way ? Will be interesting to see what the answer to that question is. 

Would you be interested in sharing your Node Red flow- or at least parts of it ?
I started working on Node Red last winter but only got it talking - haven't figured out any control or monitoring yet because I am a beginner and haven't put the time into it this summer.

Not worth the risk for $63!
Sure, I was just thinking others might be interested in that part. Not too hard, I'll work on a little tutorial.
You will need the modbustcp node

This is the code from  modbus to nodered

var base = 4114;
var EMP = msg.payload[4131-base]/10.0

var newMsg = {

jedon ,
Could you add your tutorial on this thread  ?

Someone there recently asked if anyone else had gotten Node Red to work via the network - which you have.  I had mine connected via serial.

Thanks ,

You would not be able to poll the serial port of an SL through the Ethernet port of a seperate classic, You could poll the serial port of multiple classics in follow me through one serial port but its not as easy, I agree for $63 if you are gathering Modbus over TCP/IP get a standard classic
